Bug ID: 412344
Summary: Problem setting mips flags with specific paths
Product: valgrind
Version: 3.15 SVN
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: judge.pack...@gmail.com
Target Milestone: ---
SUMMARY
Hi,
We have a bulid environment/CI system where we are cross-compiling valgrind for
various architectures. Due to the way the CI system creates it's working
directories such as ${os}-${arch} we end up with paths like
/workspace/linux-mips64/output which are included as part of the sysroot when
cross-compiling.
Our configure invocation ends up like this
CFLAGS='--sysroot=/workspace/linux-mips64/sysroot -g2 -gz -mabi=64 -O0' \
./configure --target=mips64-unknown-linux-gnu \
--host=mips64-unknown-linux-gnu \
--build=x86_64-linux-gnu ...
This trips up the following grep in configure.ac
https://sourceware.org/git/?p=valgrind.git;a=blob;f=configure.ac;hb=HEAD#l1751
It matches the 'linux-mips64' and skips the code that sets FLAG_M32 and
FLAG_M64.
STEPS TO REPRODUCE
1. create sysroot in a path with 'linux-mips64' as a component
2. run
CFLAGS='--sysroot=/workspace/linux-mips64/sysroot -g2 -gz -mabi=64 -O0' \
./configure --target=mips64-unknown-linux-gnu \
--host=mips64-unknown-linux-gnu \
--build=x86_64-linux-gnu
3. check values for FLAG_M32 and FLAG_M64 in config.log
OBSERVED RESULT
FLAG_M32 and FLAG_M64 are not set
EXPECTED RESULT
FLAG_M32='-mips32 -mabi=32' FLAG_M64='-march=mips64r2 -mabi=64'
SOFTWARE/OS VERSIONS
Linux: debian "buster"
